PowerJive USB Voltage/Amps Power Meter Tester Multimeter, Test speed of chargers, cables, capacity of power banks.
Details:
Sepecification:
Input Voltage: 3-15V
Input Current: 0.05-3.5A
Measurement error: ±1%
Capacity range : 0-19999mAh
Functions:
When the display is closed, click the button to open the display.Then click the button turns to view data in each group,click one time, the screen will display next group of data, the group of digital flash 5 seconds, after 5 seconds without any operation , the screen will come back to show the current group data. Double click the button to switch to the next group of capacity data record; Holding button (about 2-3 seconds) , current data will be deleted ;
5 minutes without any operation, the display backlit automatically shut down.
When the voltage is over than 13V or lower than 4.6V, the voltage display data flashing (frequency 1Hz), buzzer sound alarm (D-, every 5 seconds); when the voltage is higher than 15V, USB port will be shut down automatically in order to protect the device , and Buzzer will alarm (Sound: "D – D – D" repeated every 5 seconds).
When output current is over 3.1A, the electric current data will flash (1Hz frequency), buzzer will alarm (D-, every 5 seconds); when the output current is over 3.5A, USB port will be shut down automatically in order to protect the device , and buzzer will alarm ( Sound: "D – D – D" repeated every 5 seconds)
Over voltage (more than 15V) or over current (more than 3.5A) shut off output, to prevent the twice damage to the load device without monitoring, this item have to be shut down( it means just take out from power) then use again.
Notes:
Input Voltage must not over 15V, otherwise it may cause permanent damage to the equipment.
If you use "USB load resistance" (sell separately), must not work for a long time during electric current is over 3A;
To ensure the equipment universal fast charging automatic recognition function, power supply voltage shall be 4.6~15V.
